cokin Z holder and varible screw on ND filter?

I have a K&F Variable screw on filter.

I want to buy the Cokin Z series holder for GND.

It is not possible to use the Cokin Z holder with GNDs with the variable ND screw in filter?

game maker – Way to reset Varible after collision resolution – Gamemaker

I have a code that, if a player is in contact with the wall, prevents him from moving.

Other code

Is there a way with this code to reset the collision variable, and if it was not, what would be the simplest alternative? I tried to rest it at the beginning of the stage, but it did not work.
